如何通过多层次阵列寻找文本搜索（PHP） [英] How to search through multi level arrays looking for text (PHP)

问题描述

我想通过类似下面寻找pair2.php.net阵列搜索 - 这将是通过域搜索的最有效的方法是什么？与stripos函数一个循环foreach语句？

 阵列
（
    [0] =＆GT;排列
        （
            [主持人] = GT; php.net
            [类型] = GT; MX
            （PRI）=＆GT;五
            [目标] =＆GT; pair2.php.net
            [类] =＆GT;在
            [TTL] =＆GT; 6765
        ）    [1] =＆GT;排列
        （
            [主持人] = GT; php.net
            [类型] = GT;一个
            [IP] =＆GT; 64.246.30.37
            [类] =＆GT;在
            [TTL] =＆GT; 8125
        ））
 

下面是从第一个评论的建议，我的工作code - 会用不同的方式更有效？

  $搜索='secureserver.net';$ X ='不！';的foreach（$结果作为数组1 $）
{
    的foreach（$数组1 AS数组2 $）
    {
        如果（stripos函数（$数组2，$搜索））
        {
            $ X ='是的！';
        }
    }}
回声$ X;
 

解决方案

您可以使用一个for循环，并使用in_array构建在PHP中查找该值在数组中： -

in_array（'pair2.php.net'，$ sub_array）;

I would like to search through an array like the one below looking for pair2.php.net - what would be the most efficient way to search through the domain? A looping foreach statement with stripos?

Array
(
    [0] => Array
        (
            [host] => php.net
            [type] => MX
            [pri] => 5
            [target] => pair2.php.net
            [class] => IN
            [ttl] => 6765
        )

    [1] => Array
        (
            [host] => php.net
            [type] => A
            [ip] => 64.246.30.37
            [class] => IN
            [ttl] => 8125
        )

)

Here's my working code from the first comment's suggestion - would a different way be more efficient?

$search = 'secureserver.net';

$x='no!';

foreach($result AS $array1)
{
    foreach($array1 AS $array2)
    {
        if(stripos($array2,$search))
        {
            $x='yes!';
        }
    }

}  
echo $x;

解决方案

you could use a single for-loop and use the 'in_array' construct in php to look for the value in an array :-

in_array( 'pair2.php.net', $sub_array );
